Hi all, just thought that I'd compile and run the tests on my G4/450 and PIII/733 for comparison. VERY interesting results. I had to change the i value from 20,000 down to 5,000 to save time...
In any event, the results are 15s for the G4/450 and, get this, 55s for the PIII/733.
Further compounding these results was the fact that the G4 was running setiathome with OSX's lousy priority scheduling (nice 20 usually takes up no less than 15% CPU) and the PIII was devoting 100% of it's processor resources to the task.
The best part about one-off, anecdotal evidense is that it is just that ;)
(gcc 2.95 - cygwin - on the PC, gcc 3.1 on OSX) I'll get the java version and give it a whirl...

Your overall point being because Apple poses and threat to Nintendo, which Nintendo recognises, Nintendo are doomed to go out of business?
That's not what he's saying. The premise being presented is adapt/evolve or face the consequences of a rapid moving technological world. Doesn't mean the company goes out of business.

That's the Kentsfield chip not the Clovertown (Xeon) CPU but the benchmarks are interesting.
Just as expected the Quad cores are only going to be a big improvement for the software that can utilize them. Software will catch up with multicores, hopefully by Q2 07 when I'll be buying a new machine.

Funny. I find you to be the second most bigoted person I've seen so far on this thread. But that's just like, my opinion.
Calling you out on your religious garbage is not bigoted.
It's merely pointing out that until you provide some evidence for the existence of your invisible god, it might be a good idea to stop treating people like second-class humans based on the writings of 1st century nomads who didn't know enough about the realities of the universe to keep their food supplies away from their toilets.
It's pointing out that this Earth is littered with the bones of people who have been killed in the name of what you find 'sacred'.

ddtlm,
I have my theory as to why java took the lead over C in the sqrt example. There is quite a common misconception about Java that it's always slow, and there is a reason for it. Back in the early days prior to 1.2, it wasn't uncommon to see something like we did here run 10,20, or even 30 times slower then C. VM's today (1.4 /w hotspot) are much smarter than they were years ago. IMO, Hotspot makes the conventional "just in time compilers" look like a thing of the past.
Anyways, when you really think about it, Java really has an extra card up it's sleeve. Sure we tell GCC we want max optimizations, (03, etc), but GCC is limited to compile-time optimization. I think since java has adaptive runtime optimizations, specifically hotspot, the runtime optimization is what really makes the difference.
The reason why it's called "HotSpot", is literally because it looks for "hot spots" by profiling on the fly at runtime. Pretty cool, huh? Your first adaptive optimizations kick in second time the loop is ran. Not to mention the conventional JIT optimizations... code will natively compile and so you eliminate the costly overhead of bytecode translations.
Lastly, I am going to do the matrix operation you spoke about, I have to finish up some course work, so I may not get to it tonight, but as soon as I can devote some time to it, I will.

Do you have evidence of this just out of interest? I too was surprised to read this, so I'd be interested if you had evidence the other way.
zero evidence, other than my gut feeling.

A smart hacker will simply feed Safari the data it looks for when verifying a file is an installer. Once that's done, do what you want with the person's computer. It isn't rocket science, it just takes time and effort, something many hackers would rather spend on windows-based PCs.
All successful malware includes privilege escalation via exploitation. This does not. That is why malware never has become successful in OS X and is becoming less successful in Windows. The big issue with Windows in the past was the default account in Windows XP (admin) runs with elevated privileges by default so privilege escalation was not required for system level access.

Most Islamic countries are not inhabitable by homosexuals or religious minorities, your mileage may vary.
The biggest muslim population right now is Indonesia, and they tried banning Christians from using Allah to describe their God. They're also trying to ban the Ahmadiyah sect...
I don't think France or Britain are responsible for Iran's strict implementation of Islamic law and ruthless persecution of dissidents, and to claim that they are responsible is insulting to Muslims because it implies they're far too reactionary to deal with anything using Reason. Just like people who want to ban qur'an burnings and blasphemy because they're afraid of how muslims might react. Are Muslims animals who are so easily goaded? No, they're human beings so they should be expected to act responsibly and not go on rampages at the slightest provocation.
@ the underlined: It's almost like I couldn't even see you move the goalposts :rolleyes:
As for your rant at the end, you've completely missed my point, then used your very own to rant against with your twisted logic. In fact, it was the same exact tactic I was laughing hysterically (in a morbid way) about listening to Hannity in the car last night.
Have fun with your misunderstandings.

You all seem to be ignoring the elephant in the room.
The spiralling demand for still more energy.
Someone mentioned California, and their inordinate requirement for 'more power' <ugh, ugh ... thank you Tim>.
How about we stop with the over-population, and working everyone 24-7?
Farmers used to get up with the Sun, and went to bed when it set.
If there is a lost tribe still somewhere that is flourishing, I hope that they never get "discovered".
I hope you're not including me in that as I've posted several times on the very subject.I'm not a Malthusian but I agree that human population is something we need to look at,every child a wanted child and cared for child for instance.Why do westerners use so much energy?Because they are not in touch with their environment,airconditioning in cars and homes?wtf for there are technologies hundreds of years old that can deal with that.To me it appears a lot of people work harder and harder for less and less.Bah humans in general are eejits.

I am not concerned with malware that requires user intervention and a few clicks to install things. I am more concerned with malware that installs silently without you seeing any pop-ups or stuff like that.
Kind of like those pwn2own contests I think are over-rated. "Pwn" my machine without me having to click anything, visit any website or anything. I'll just boot my machine, leave it at the login screen and let you do your thing. You can't touch it physically, just find a way in.

Superb. Replace one fuel reliance on the Middle East with another. Genius idea.
I think you confuse cooperation with exploitation by paying those in the Sahara (which is Africa by the way) a fair price for their resource it's a win win situation,applying 19th century ideas to a 21st century problem isn't going to work.It would raise living standards in Saharan Africa to European levels very quickly.

I don't want to seem judgemental, but the last thing I ever plan on doing is selling my G5 Quad. I mean like I will have my G5 Quad until I DIE. Why would you do that? It runs classic. It runs Adobe native. It is pretty fast for email and word processing. ;) And it runs dead silent. It's the perfect backup for when the Mac Pro goes down. At the very least it makes for a great HDTV player and recorder with EyeTV 500 or Hybrid attached.
What was your reasoning?
And what's up with you not knowing the 8-core was coming? This is very old news. Some of us have known since early this year. :confused: :eek:
i wish i could have kept the Quad for some of those reasons mentioned, but it's purely down to financial reasons, i simply wouldn't be able to afford keeping both. I'm a film-maker just starting out, so i'm not getting a very steady income that is related to work done with a computer to be able to justify such expenditures etc.. firstly i got a decent price for my quad, i wouldn't have sold otherwise, it'll only be a few hundered pounds for me to upgrade to a mac pro, but i sold partially because i'm one of those who likes the newest etc.. but main actual reasons are
1) I mainly use HDV with Final Cut Studio, so the performance bump would be very useful for me, obviously more of a luxury, FCP worked fine on the quad, but anything better is worth it. 2) I use adobe but any of the few deadlines i have don't really rely on the use of adobe software, but i know in a few months the use of adobe stuff will be much more important to me and i'll have to buy a license, CS3 will probably be out by then as well as other Universal Binary converts, and i imagine the Quad will only be worth having for people needing a backup machine, the value of it will drop like anything, no?? rather sell now while the value of it is still fairly high, and especially because they are out of stock everywhere. 3) I get a windows capable machine that is powerful enough to let me use some software i wouldn't have been able to use before on my 2.4ghz, 1gb PC, as well as run games properly on my 30". Buying a seperate similar specced Windows PC wouldn't be worth it for me, but the situation with bootcamp is just perfect for my needs.
If i was running a steady business, no way would i have sold the Quad, but i'd rather sell now while i can afford to be sans mac, rather than down the line when i know the mac pro will be extremely sought after and get bottom dollar for the quad.
oh i knew the 8-core was coming out, i just didn't know it would be this soon, i've only recently started getting into the 'underground' gossip of macs, and i don't know where i got the idea from but i thought the octo would be around Q1/2 of next year, and i would just have just done the upgrade myself if it warranted it. Anyway i was able to finish all my work this weekend before i shipped it today, so in a strange way i have a sort of holiday thanks to this news, though as a recent mac convert i can't believe i used to live like this, already missing her. :(

It decompressed the zip file and executes code to launch an installer. This is considered a safe action because the user still has to continue to run the installer.
Installation of MacDefender via the installer requires password authentication by the user.
So Safari auto-downloads, unarchives and auto-executes something, but you think it is safe because it's an installer ? :confused:
I'm sorry, but I'm still curious about the "auto-execute" part. Why would it run the installer automatically after decompressing it. That sounds quite "unsafe" to me. Even without administrator privilege, that means code can still run that can affect the current user's account.
like there's no such thing as a virus for Mac...

How does that matter? Last I heard, iPods didn't cost $.99. Plus Apple doesn't get $.99 per song, they get roughly $.34. iTMS makes Apple money, sure... but compared to the amount of money iPods make them there is no comparison.
I've said it over and over again, and so has plenty of others... iTMS exists to sell iPods.
I've used iTMS before I bought my iPod Shuffle (way cool!) to simply download music and burn to it CDs. Beats the inconvenience of running out to Walmart and buying the CD for even more money. And I get to search and preview. This is the best way to buy music WITH OR WITHOUT a portable music player.
Also, $0.34 is a nice profit per song * 300+ million songs and growing. Not bad business for just pushing bits! :cool:
Off Topic: Any with an iPod Shuffle think the plastic is reminiscent of Lego (R) plastic?
